Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Walnut (Juglans regia) has a history of traditional use for supporting hair health, particularly in Ayurvedic and folk medicine practices. Walnut oil is sometimes applied topically and walnut kernels are consumed with the belief that their nutrient content—such as omega-3 fatty acids, biotin, vitamin E, and antioxidants—can help prevent hair loss or promote hair growth. However, the evidence for these claims comes primarily from tradition and anecdotal reports, not robust clinical studies.

Scientific investigations into walnuts and hair loss are scarce. Some laboratory studies and reviews suggest that nutrients found in walnuts may be beneficial for general hair health because deficiencies in those nutrients (like biotin or omega-3s) are linked to hair thinning. However, no direct, high-quality randomized controlled trials have demonstrated that walnut consumption or topical application specifically prevents or treats hair loss in humans.

In summary, while walnuts are nutritious and their components theoretically support hair health, their use for hair loss or thinning is mainly grounded in traditional practices rather than strong scientific evidence.
